@lesbunny I didn't get into it myself until the last episode of GAP was released.
Long before that, there was speculation that Freen and Becky could be a couple in real life.
I was irritated that after GAP they appeared together as #freenbecky. #monsam I would have understood, then it had been their series characters.
But #freenbecky made it look like a "real" couple though. They never confirmed that but never denied it either. And made a lot of money with it.
Some always suspected "fanservice", that seems to be common in Thailand (I don't know about that, I'm from Europe).
